Evaluation of the Safety and Preliminary Immunogenicity of Inactivated Rotavirus Vaccine (Vero Cell) in Healthy Population: a Randomized, Double-blind, Placebo Parallel-controlled Phase I Clinical Trial
This study is a randomized, double-blinded, placebo-controlled, Phase 1, dose-escalation study to evaluate the safety, reactogenicity and immunogenicity of Inactivated Rotavirus Vaccine (IRV) performed in healthy adult (aged 18-49 years), adolescent (aged 6-17 years) and infant subjects (aged 2-71 months). Primary objectives of the clinical trial include assessing the safety and tolerability of IRV given at two and three dose levels and comparing the safety and tolerability of IRV after each vaccination, between dosage groups, and by pre-vaccination rotavirus immune status. Secondary objective of the clinical trial is immunogenicity evaluation after each vaccination, between dosage groups, and by pre-vaccination rotavirus immune status.
